I recently ran a rather time intensive calculation and plotted the results in a histogram by simply called Histogram[data]. However, because of a rather serious error on my part, I recently lost my original data and all I have is the histogram plot.

I need to change the vertical cut-off on the histogram (it will cut off any bars with an event count >= N). I can hover over the bars and read the values, so I know the information is there, but how can I change the value of N for the vertical cutoff?

I recieve an error saying the FrontEnd 'If is not a graphics primitive or directive.

I cannot regenerate the histogram, I only have the graphic.

@Nikki, I updated with the answer showing how to use the graphic you have. Regarding the error message in your first comment, I am not getting any error messages (using Windows Vista 64bit, Mathematica Version 9).

That's effectively what I tried earlier... hmm... does it still work for you if you quit the kernel and then try it?

Yes, it does work with a fresh kernel. Just checked that it also works in Version 8.0.4.0. Do you get the same error message when you use the methods on a new histogram? If not, perhaps you can post the FullForm of your graphic to see if there is anything specific that is causing the issue. (To get the FullForm of your graphic, just copy-paste it inside the brackets in FullForm[] in a new cell.)
